This plugin adds the site icon option to Settings -> General.
If you disable or do not use the customizer, then you will have trouble updating the site icon. The site icon is used for favicons, and the new oEmbed feature. This plugin makes the site icon editable from the general settings page.
The plugin is a modified version of Jetpack\’s site-icon module.
Note: The plugin does not remove the ability to change the site icon from the customizer. It only adds another way to change the site icon.

Move Site Icon To Settings

Thanks for releasing this little gem!

Maybe an idea to promote this a bit more? The Customizer becomes more and more irritating, with 4.7 around the corner there's even the added CSS editor. The only useful thing in there is the site icon, so time to dump the entire thing and install your plugin!

Great

I found a nice theme but it didn't include the site icon settings in the Customizer. This plugin made it simple and easy to add a site icon without code. Thanks!

Works great in 4.7
